H. E. KLEFFEL APPARATUS FOR DELIVERING AIR TANGENTIALLY TO AN AIRREGISTER Filed Sept. 24, 1923 INVENTOR HARRISON E. KLEFFEL HIS ATTORNEYPatented Dec. 16, 1924 UNITED STATES [PATENT OFFICE.

HARRISON KLEFFEL, NEW YORK, N. Y.

I Application filed September 24, 1923, Serial No. 664,518. L

i To all whom it may concern:

Be it known that I, HARRISON E. KLEFFEL,

.a citizen of the United States, residing on Manhattan Island, in thecity, county, and

State of New York, have invented-certain new and useful Improvements inApparatus for Delivering Air Tangentially to an Air Register; and I dohereby declare the following to bea. full, clear, and exact descriptionof the "invention, such'as will'enable others skilled in the art towhich it appertains to make and use the same.

The invention relates to air control registers for fuel burners, and hasfor its object to provide a scientifically proportionedscroll casingSurrounding an air control register that will convert the pressuredifference existing between the furnace and the draft pressure into thehighest velocity so that the -maximum quantity of air can enter theregister uniformly with equal distribution.

A further object is to provide a register casing that will deliver airuniformly to.

the register with less drop in draft pressure,

and greater wdischarging capacity.

A further object is to provide a casing to fitv on any standard aircontrol register and provide an inlet duct that may point in anydirection. i

The foregoing and other features of my invention will now be describedin connecmore particularl tures which I be ieve to be new and of my owninvention.

tion with the accompanying drawing forming part of this specification,in which I have represented my air register in its preferred form, afterwhich I shall point out in the claims those fea- In the drawings'faFigure 1 is a diagrammatic sectional view of my register and easing.

Figure 2 is a front view thereof.

In the carrying out of my invention the refractory wall 1 ofanyosuitable furnace is provided with an opening 2, standard air re'ster 3, atomizer 4. The register 3 is provi ed with means 5 shown asshutters or doors, to regulate the air entering the furnace, all ofwhich is common to fuel burners 51d requires no further detaileddescription herein.

Surrounding the air register 3 I provide a casing 6 shaped like a volutescroll not unlike the oasing used in hydraulic turbines of the volutetype and provided with a tangential inlet 7. .This is mounted to a plate8in the furance front and adapted to V .be rotated about the axis of theburner and To effect this, the

held in any position. plate 8 may have a flange 8' provided with agrooved edge, in which groove the edge of the casing 6 fits. Thefriction between the two parts is normally sufiicient to hold th casingin any adjusted position.

By referring specifically to Figure 2 it will be readily understood thatas the air enters the inlet 7 the shape of the volute air] passagechanges the draft pressure into increasing velocity, thereby equalizingthe amount of air entering the airregister between the regulating means5.

The volute chamber 6 gradually contracts as the air moves into theregister which maintains the velocity of air.

I wish it distinctly undersood that my apparatus herein described andillustrated is in the form inwhich I desire to construct it and thatchanges or variations may be made as may be convenient or desirablewithout departing from the salient features of myinvention andItherefore intend the following claims to cover such modifications asnaturally fall within the lines of invention.

I claim:

1. An air; register, a casing surrounding the same and provided with atangential air inlet and means for mounting said casing to permit theair inlet to be pointed in any directionin one plane 2. air register, acasing surrounding the same and provided with a tangential air inlet,and a mounting for said casing which permits its rotation to point theair inlet in any direction' in the plane of rotation.

3. An air register, a casing surrounding the same and provided with anair inlet, the

space between the casing and the register being in the form of a singlevolute scroll 5. An air register fitting in an opening in a furnacefront and adapted to regulate the amount of air passing to the furnaceand a casingsurrounding-the register'and provided with an air inlet, theair "passage between the casing and register having the form of a singlevolute scroll.

6. An air registena casing surrounding the same and provided with an airinlet, the space between the casin and the register decreasin as thedistance roin the inlet increases, and means for mounting the casing topermit the air inlet to be pointed in varying directions.-- g An airregister, a casing surrounding the same and provided with a tangentialair inlet, the space between the casing and the register being in theform of a volute scroll, and means for mounting the casing to permit itto be moved to point the air inlet in all directions in one plane.

8. An air register, a casing surrounding the same and having atangential air inlet, means for regulating the amount of air passingthrough the register, the passage between thecasing and the registerbeing in "9. An air register fitting in an opening in a furnace front,and a casing surrounding the-air register and provided with, a singletangential inlet, said casing being formed to deliver air tangentiallyin substantially uniform amounts to all portions of the air re 'ster. Y

' testimony whereof I afix my signature in the presence of twowitnesses,
